Haub ate one of those sugary snacks every few of hours everyday for nearly two months. He skipped traditional meals, opting instead to limit his junk food intake to 1,800 calories a day.

"Day one was the toughest," he said. "I've done low carbohydrate, low fat, and it was one of those things where I didn't know if I'd make it through the weekend."

He stuck with it and ended lowering his bad cholesterol and his pant size. He lost nearly 30 pounds.

"I think with the weight loss, [my] sleep apnea and snoring issues have decreased, which I think have enhanced [my] quality of life and energy level," he said.

"That's usually the stuff you try and stay away from when you're dieting," said Camillia Marcs, but she was interested in the diet. "If I could lose 30 pounds on that diet, yeah, I'd try it!"

We took three grocery bags full of junk food to Tami Lawrence, a registered dietician.

"Bottom line: if you're taking in fewer calories than you're expending, then you're going to lose weight," she said.

But Lawrence warned that it may not be the healthiest way to shed the extra pounds.

"It scares me," she said. "There could be bone loss, muscle wasting if there's not enough protein." All that sugar and fat could also lead to heart problems.

Lawrence didn't recommend the diet, but was interested in more information.

"I'm hoping he will follow this up with a study in a few months."

The professor's diet also seemed to improve his other health stats. His bad cholesterol dropped 30 points and good cholesterol shot up. And his body mass index went to 28.8 percent which is considered overweight to a healthy 24.9 which is normal.
